Multi-Layer Barrier Structure Engineered with PET/Aluminum Foil/PE or PET/CPP laminates providing exceptional protection against oxygen, moisture, UV light, and microbial contamination. The aluminum foil core (6-9 μm) ensures light-blocking opacity, critical for preserving photosensitive fruits like berries and grapes Optional gel-assisted bacterial cellulose (BC) layers offer a microplastic-free, biodegradable alternative with natural antimicrobial properties, extending shelf life by inhibiting mold and bacterial growth (e.g., E. coli O157:H7 inhibition >90%) Fruit-Specific Preservation Technologies Anti-fog coating prevents condensation inside packaging, reducing spoilage in high-moisture fruits (e.g., strawberries, citrus) Perforated breathable designs for tropical fruits (e.g., pineapples) enable gas exchange, minimizing anaerobic decay Modified atmosphere compatibility adjusts O/CO levels to slow ripening, extending freshness by up to 30% compared to conventional films Eco-Certified Sustainability Integrates recyclable aluminum and GRS-certified polymers (e.g., PE, PET) with biodegradable BC/GG/QM multilayer options decomposing within 8 weeks in soil Compliant with FDA 21 CFR, EU 10/2011, ISO 22000, and BRC standards for food safety Automation & Customization Flexibility Heat-sealable surfaces (130°C-160°C for PE layers ensure airtight seals on high-speed filling lines, compatible with vertical form-fill-seal (VFFS) machines Supports up to 12-color gravure/flexographic printing for branding, with customizable widths (150-1,200 mm), lengths (100-6,000 m), and finishes (matte/gloss/embossed) Enhanced Durability for Logistics Puncture-resistant and tear-proof construction withstands rough handling during transport Temperature resilience (-40°C to +70°C storage ensures integrity in cold-chain logistics for frozen fruits Product Specifications Material Composition: Standard: PET (12-25 μm)/Aluminum Foil (6-12 μm)/PE (50-100 μm) Biodegradable: BC/GG/QM multilayer with antimicrobial quaternized chitosan microspheres (QM) Thickness Range: 20-200 μm (recommended 70-120 μm for berry packaging 10 Barrier Performance: Oxygen Transmission Rate (OTR): ≤0.05 cm³/m²/day (aluminum-based); ≤50 cm³/m²/day (breathable perforated variants Water Vapor Transmission Rate (WVTR): ≤0.1 g/m²/day Mechanical Properties: Tensile Strength: ≥150 MPa (longitudinal), ≥120 MPa (transverse) Seal Strength: 5-10 N/15mm Printing & Finishing: High-definition CMYK/PANTONE printing (up to 12 colors) Anti-fog, anti-static, or metallic finishes Certifications: FDA, EU 10/2011, ISO 22000, BRC, REACH, RoHS Packaging & Logistics: Rolls protected in dust-free cores; customizable dimensions (width: 150-1,200 mm; length: 500-6,000 m) FOB Shenzhen; lead time 7-15 days
